| Optical wavelength | 200 nm–2000 nm |
| Optical pulse duration (800 nm, full width at half-maximum; FWHM) | 30 fs |
| Achievable time resolution (FWHM) | 70 fse |
| Bragg angle range of Von Hamos spectrometers | 60°–75° |

a.
This corresponds to the focal beam size obtained with the Kirkpatrick-Baez (KB) mirrors.32
b
This corresponds to the focal beam size obtained with the CRLs.21
c
XFEL intensity after the four-bounced Si(111) reflections by the double channel-cut crystal monochromator21 implemented at SACLA BL3.
d
This is the typical case of SACLA BL3.
e
The time resolution depends on the optical pulse duration, the jet thickness, and other experimental conditions. This value was evaluated in Ref. 16.
